Mariah Carey was so excited about President Barack Obama's re-election that she released a new song in his honor. Beyonce popped up on Instagram with a rebuke for Mitt Romney, while Romney supporter Elisabeth Hasselbeck sent out a disappointed but conciliatory tweet urging a divided United States to become one.

Celebrities, who voiced their opinions loudly during the election, continued to speak their minds after the ballots were counted.

Cameron Diaz, promoting her film "Gambit" in London, said she was worried about the election as she fell asleep.

"I was terrified that I was going to wake up to a total embarrassment for our country and that today would be a very different day for me," she said Wednesday. "But I was so thrilled."

Romney supporters Donald Trump and Ted Nugent ranted on Twitter after the election that the country is doomed, while Spike Lee and Russell Simmons celebrated Obama's victory and the diverse electorate behind it.

NBC News anchor Brian Williams called attention to Trump's series of tweets Tuesday while covering election returns, saying the real-estate magnate and reality-TV star had "driven well past the last exit to relevance and veered into something closer to irresponsible" with his posts.

"This election is a total sham and a travesty. We are not a democracy!" Trump tweeted. "Let's fight like hell and stop this great and disgusting injustice! The world is laughing at us."

Nugent was similarly upset - and expressive - Wednesday morning.

"Pimps whores & welfare brats & their soulless supporters hav a president to destroy America," he wrote. "Goodluk America u just voted for economic & spiritual suicide. Soulless fools."

He concluded with: "I cry tears of blood for The Last Best Place & the warriors who died for this tragedy."

Hasselbeck shared a more measured response, tweeting, "(Hash) momentofpeace: You cannot love the game only when your player wins. We remain to be the greatest nation and (at)BarackObama is OUR President." Mark Cuban, meanwhile, extended a virtual olive branch to Trump, writing, "I know it was a rough night for u," and inviting Trump to join him in raising funds for victims of Hurricane Sandy.

Spike Lee was among the most vocal Obama supporters online after the election, using his Twitter feed to blast the Republican party.

"Great Lesson. This Is Not Ike's 1950's USA. Complexion Of This Great Country Has Changed-A True Melting Pot. The GOP Is Stuck In A Time Warp. YO," the filmmaker wrote Wednesday. "GOP WAKE UP. This Is Not" LEAVE TO BEAVER.FATHER KNOWS BEST OR MAYBERRY R.F.D." THE 21st CENTURY. And Dat's Da 2nd Term Truth, Ruth. YA-DIG??"

Beyonce also gloated a bit, posting a photo on her blog that read, "Take that Mitches." It was accompanied by another photo of the singer wearing a "Texans for Obama" T-shirt.

Carey released a new song, "Bring It On Home," online Wednesday to celebrate the president's victory. She first performed the song at an Obama fundraiser over the summer, said Carey publicist Cindi Berger.

The pop star also shared her support on Twitter.

"Congratulations to our beloved President Barack Obama, our spectacular First Lady Michelle Obama & the adorable Malia & Sasha. We love you!" Carey wrote. "INCREDIBLE SPEECH!!!!!! Watching in a room full of diverse people-all truly moved. Thank you America for President Obama-4more yrs."

Rapper Young Jeezy released an election-inspired song of his own Wednesday called "We Done It Again". He recognized Obama's 2008 election with a track called "My President Is Black".

Russell Simmons also acknowledged the diversity of Obama supporters in a blog post Wednesday called "Forward!"

"This is no time for triumphalism, because we are still in an economic crisis and we still have deep social divisions that must be dealt with," he wrote. "But we have to absorb, as a country, as a NATION, that first and foremost, AMERICA IS CHANGING... We cannot fight demographics by ignoring women, Latinos, blacks, young people, and gays who gave their lives for our country.

"The middle class and poor need support," he continues, "and every politician who is not ready for this change should wake today and realize that minorities will wait in line into the early hours of the morning to vote them out of office. Forward, we go."

Scores of other stars - including Tony Bennett, Cher, Shakira, Lady Gaga, Jessica Alba and Samuel L. Jackson- celebrated Obama's victory on Twitter.

Others, including filmmaker Ron Howard and actors Rob Lowe and James Van Der Beek, say it's time to move past the election toward mending the nation.

"To all the winners (and losers) tonight: Politicians run campaigns. Leaders strike compromises," Van Der Beek wrote. "Time for everyone to shift gears now (hash)please."
